ViaGen began by offering cloning to the livestock and equine industry in 2003, [20] and later as ViaGen Pets included cloning of cats and dogs in 2016. [21] ViaGen's subsidiary, start licensing, owns a cloning patent which is licensed to their only competitor as of 2018, who also offers animal cloning services. [22] (Viagen is a subsidiary of ...
Animals are generally much harder to transform and the vast majority are still at the research stage. Mammals are the best model organisms for humans. Livestock is modified with the intention of improving economically important traits such as growth rate, quality of meat, milk composition, disease resistance, and survival.
High fetal and neonatal death make the process very inefficient. Resulting cloned offspring are also plagued with development and imprinting disorders in non-human species. For these reasons, along with moral and ethical objections, reproductive cloning in humans is proscribed in more than 30 countries. [31] Most researchers believe that in the ...
Genetically modified animals are animals that have been genetically modified for a variety of purposes including producing drugs, enhancing yields, increasing resistance to disease, etc. The vast majority of genetically modified animals are at the research stage while the number close to entering the market remains small.

Scientists have cloned the first rhesus monkey, a breakthrough that could help advance medical research but has drawn criticism from an animal welfare group. New cloned monkey species highlights ...
In January 2019, scientists in China reported the creation of five identical cloned gene-edited monkeys, using the same cloning technique that was used with Zhong Zhong and Hua Hua, and the same gene-editing CRISPR-Cas9 technique allegedly used by He Jiankui in creating the first ever gene-modified human babies Lulu and Nana. The monkey clones ...
Genetically modified mammals are mammals that have been genetically engineered.They are an important category of genetically modified organisms.The majority of research involving genetically modified mammals involves mice with attempts to produce knockout animals in other mammalian species limited by the inability to derive and stably culture embryonic stem cells.
Cloning has been used by scientists since the 1950s. [5] One of the most well known clones is Dolly the sheep. Dolly was born in the mid 1990s and lived normally until the abrupt midlife onset of health complications resembling premature aging, that led to her death. [5] Other known cloned animal species include domestic cats, dogs, pigs, and ...
